Whistler propagation in the plasmapause [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2013
Variations in plasma density and magnetic field have a strong effect on the propagation of very low frequency waves in the whistler mode. Numerous studies have established that field‐aligned density irregularities (sometimes called ducts) symmetrical relative their axis can effectively guide whistlers along the ambient magnetic field. In this paper, we

Plasmaspheric dynamics resulting from the hallowe'en 2003 geomagnetic storms [PDF]

open access: yes, 2009
Cross-phase-derived plasma mass density trends during the Hallowe'en 2003 geomagnetic storms are presented for 38° magnetic latitude 63° (1.61 ≤ L ≤ 5.10), using data from the SAMNET (Subauroral Magnetometer Network), BGS (British Geological Survey), and

Remote sensing the plasmasphere, plasmapause, plumes and other features using ground-based magnetometers

open access: yesJournal of Space Weather and Space Climate, 2014
The plasmapause is a highly dynamic boundary between different magnetospheric particle populations and convection regimes. Some of the most important space weather processes involve wave-particle interactions in this region, but wave properties may also ...

Statistics and Empirical Models of the Plasmasphere Boundaries From the Van Allen Probes for Radiation Belt Physics

open access: yesGeophysical Research Letters, 2022
We deduce the electron plasma density from the NASA Van Allen Probes Electric Field and Waves and Electric and Magnetic Field Instrument Suite and Integrated Science measurements and extract the plasmasphere boundaries throughout 2012–2019.

Proposal for an ionosphere/plasmasphere monitoring system [PDF]

open access: yesAnnales Geophysicae, 1994
A space-based satellite system suited for long-term monitoring of the Earth's ionosphere/plasmasphere systems is proposed. The monitoring system consists of a network of radio beacon satellites capable of measuring the ionospheric and plasmaspheric ...

The distribution of plasmaspheric hiss wave power with respect to plasmapause location

open access: yesGeophysical Research Letters, 2016
In this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth.

Alfvén waves in the magnetosphere generated by shock wave/plasmapause interaction

open access: yesSolar-Terrestrial Physics, 2019
We study Alfvén waves generated in the magnetosphere during the passage of an interplanetary shock wave. After shock wave passage, the oscillations with typical Alfvén wave dispersion have been detected in spacecraft observations inside the magnetosphere.

Narrow-band emission with 0.5 to 3.5 Hz varying frequency in the background of the main phase of the 17 March 2013 magnetic storm

open access: yesSolar-Terrestrial Physics, 2016
We present results of the analysis of an unusually long narrow-band emission in the Pc1 range with increasing carrier frequency. The event was observed against the background of the main phase of a strong magnetic storm caused by arrival of a high-speed ...

Observations of the ionospheric projection of the plasmapause

open access: yesGeophysical Research Letters, 2008
We demonstrate a method for extracting the ionospheric projection of the plasmapause (PP) from DMSP measurements of the H+ density in the topside ionosphere. The results agree well with PP locations derived from images of the plasmasphere acquired by the IMAGE spacecraft during a 72‐day period in 2001.

Empirical plasmapause models from magnetic indices [PDF]

open access: yes, 2003
We use a database of CRRES in situ observations of plasmapause crossings to build empirical models of the plasmapause location as a function of geomagnetic indices.
